document.write( "Question 1018568: Write an algebraic expression then solve. There is a room that is 22 feet long, by 15 feet wide, and 8.5 feet tall. This room has a door that is 36 inches by 84 inches, and two windows that are 30 inches by 42 inches each. A small can of paint will cover approximately 195 square feet of wall. How many small cans of paint will you need? \n" ); document.write( "

The perimeter of the room is 2 x (22+15) = 74 feet. \r
\n" ); document.write( "\n" ); document.write( "74 * 8.5 = 629 sq ft.\r
\n" ); document.write( "\n" ); document.write( "The door is 36 * 84 = 3024 sq inches\r
\n" ); document.write( "\n" ); document.write( "The windows are 30 * 42 * 2 = 2520 sq inches\r
\n" ); document.write( "\n" ); document.write( "Total 5544 sq inches to subtract. 144 sq inches are 1 sq ft, so 5544/144= 38.5 sq ft.\r
\n" ); document.write( "\n" ); document.write( "629 - 38.5 = 590.5 sq feet, or 3.03 cans. \r
\n" ); document.write( "\n" ); document.write( "The problem states \"approximately,\" so we don't know if they underestimate or overestimate. It's too close to say whether the 4th can will be needed.
